I am trying to graph my PCA to look at what species are grouped together for future analysis in my project. My problem is the graph is unreadable and I am not sure how to make it more appealing and useful. Can I adjust the label size or color code each species some how? Or can I change the numbers underneath to dots or remove them completely?
To help us help you, could you please prepare a reproducible example (reprex) illustrating your issue? Please have a look at this guide, to see how to create one:
I added some of my data and the code that I am using. I really need advice on how to space the labels or color code the species. The current code and data is running fine I just dont know if there is a way to make it readable.
Yes, the SpeciesData is my own personal data so just running this code in r will not work. I put an example data frame in the post. I cant really provide you with the data because its very large, I am not sure I am allowed to as a grad student and there is no way for me to upload and excel file or r file. You can reproduce a similar graph be replacing "SpeciesData" with "mtcars".
It still produces the same issue, labels are overlapping and unreadable. Its mainly just a design question, is there a way to make it look better? A diferent way of graphing or a command that I am missing?
